Most of its time is pend in the evualation code but that is nomal. Also a lot of time is spend in the capture move generation and the in check function. If i could speed of these things i would get a large pay off. But ther is another question involved. Iám not realy a good prograamer and i just want to learn more about efficient programming. SO if this will only give a small benefit i would be (partly) happy. Reagrds Jan Willem
